GEOLOGICAL SURVEY OF THE TERRITORIES. 275 



Habitat: Found throughout Wyoming, Colorado, Utah, and Northern 

 New Mexico, on the elevated table lands and ridges. 



[Note. — For explanation in regard to my unfortunate mistake in des- 

 cribing this species as new, and thus adding another synonym to the 

 already too long list, see previous note under Boopedon nubilum.] 



The female is seldom pruinose ; occiput, brown ; pronotum, reddish- 

 brown, varied with dots and lines of yellow. The posterior lobe of the 

 pronotum in each sex is densely punctured, but that of the female inter- 

 sected by irregular, slightly-raised lines. 



Oe. cincta, Thos. Syn., Oe.cinc ta, Thos. (Proc. Acad. Nat. Sci., Phila., 

 1870, p. 80.) — Female: Very similar in appearance and coloring to the 

 male of Oe. aequalis, (Say.) but in the carvings of the head approaching the 

 Tomonoti, (Sauss.,) of which Oe. sulpliurea (Burin.) may be taken as the 

 North American type. The vertex channeled ; the margins strongly 

 and sharply elevated, waved, descending; truncate squarely in front ; a 

 slight median line visible. Frontal ridge vertical, straight, sulcate, 

 narrowed immediately below the antennae, expanding at the base, 

 reaching the transverse suture ; lateral carinas distinct, divergent. Pro- 

 notum rugose, tricarinate, truncate in front, angled at the posterior ex- 

 tremity; median carina only a raised line, cut by incisions land 3; 

 lateral carinas distinct on the posterior lobe, obliterated in front, coarc- 

 tate in front, expanding posteriorly; incision 3 situated before the 

 middle. Elytra narrow, passing the abdomen one-third their length. 

 Wings nearly the same length. Posterior femora not passing the ab- 

 domen. Antennae passing the pronotum slightly. 



Color (siccus) : Rusty brown, varied with lighter and darker shades. 

 Face and the sides of the pronotum yellow, mottled with brown ; two 

 black bands pass round the front, one immediately above, and the other 

 just below the antennas, (the lower a little broader than the upper;) con- 

 verging behind these, they pass through the eye (plainly to be seen in a 

 fresh specimen) and become a single black stripe behind the eye, which 

 reaches to the posterior incision of the pronotum, decreasing in width 

 as it passes along the laferal angle. Pronotum ash-colored on the dor- 

 sum ; posterior lobe palest, with minute brown tubercles scattered over 

 it; a dark-brown spot on each side. Elytra brown, darkest next the 

 base; semi-transparent at the apex. Wings transparent, yellow next 

 the base; apical half dusky ; this dark marginal band is broad in front, 

 tapering toward the inner angle but does not reach it; stretches along 

 the front sub-margin nearly to the base ; is somewhat darker at the 

 inner and outer borders, reaching to the apex. Posterior femora red- 

 dish with two oblique darker bands on the outer face, and three black 

 bands inside. 



Dimensions : Length, 1 inch ; to tip of elytra, 1.26 inch ; to end of 

 pronotum from vertex, .31 inch ; femora, .54 inch ; tibiae, .44 inch. 



Habitat : Northeastern New Mexico. 



Oe. carlingiana, Thos. Syn., Oe, carliniana, Thos. (Proc. Acad. Nat. 

 Sci., Phila., 1870, p. 81.) — Female : This species at first sight has much 

 the appearance of Oe. Carolina, (Linn.,) but an examination of the head 

 or thorax, or spreading the wings, will soon undeceive the observer. 

 Although a little smaller than that species, it is more robust, compared 

 with its length. The carving of the head is much the same as Oe. cor- 

 allipes. Occiput short, sub-convex, not ascending ; vertex very broad, 

 slightly deflexed ; the broad, shallow, central foveola divided by a me- 

 dian carina into two elongate pentagonal spaces, the median carina and 

 margin next the eye being the longest sides; the lateral shallow foveoloe 

 triangular ; at the top of the frontal ridge is a lunate depression ; frontal
